How can jQuery detect changes to a url?
jQuery 如何检测对 url 的更改？
For example: If a user goes to a page site.com/faq/nothing shows, but if he goes to site.com/faq/#openjquery detects it and does something.
例如：如果用户进入一个页面site.com/faq/什么都没有显示，但是如果他进入site.com/faq/#openjquery 会检测到它并做一些事情。

You can use the hashchangeevent.
您可以使用hashchange事件。
function hashchanged(){
var hash = location.hash.replace( /^#/, '' );
//your code
}
window.addEventListener("hashchange", hashchanged, false);
or integrate a jquery hashchange plugin
或者集成一个jquery hashchange 插件
$(function(){
// Bind the event.
$(window).hashchange(hashchanged);
// Trigger the event (useful on page load).
hashchanged();
});
function hashchanged(){
var hash = location.hash.replace( /^#/, '' );
//your code
}

Simply look at window.location.hashon page load:
只需查看window.location.hash页面加载：
$(document).ready(function() {
if(window.location.hash === "open")
{
//Show something
}
});
Or bind to the hashchangeevent of the window:
或者绑定到hashchange窗口的事件：
$(document).ready(function() {
$(window).hashchange(hashchanged);
});
function hashchanged()
{
//Show something
}

Try this:
尝试这个：
if (window.location.hash) {
// Fragment exists, do something with it
var fragment = window.location.hash;
}
Just for reference, the part of a url specified by the #is called a 'fragment'
仅供参考，由 指定的 url 部分#称为“片段”

If you have a url of site.com/faq/#open, then you can do
如果你有一个 url site.com/faq/#open，那么你可以做
var hash = window.location.hash
to get hash = 'open'
要得到 hash = 'open'
